Even STDs that cause no breaks or open sores for example, chlamydia, gonorrhea, trichomoniasis can increase your risk by causing inflammation that increases the number of cells that can serve as targets for HIV. Treatment is a powerful tool for preventing sexual transmission of HIV. But it works only as long as the HIV-positive partner gets and keeps an undetectable viral load.
Here are some things to consider when deciding whether treatment as prevention is right for you and your partner:.

What is AIDS? - HIV
You may have thought that these diseases aren't your problem and that only younger people have to worry about them. But, anyone at any age can be infected with HIV. HIV human immunodeficiency virus is a virus that damages and weakens the body's immune system—the system your body uses to fight off infection and disease.
Having HIV puts a person in danger of experiencing other life-threatening infections and certain cancers. When the body cannot fight off infections and some other diseases anymore, HIV can lead to a serious illness called AIDS acquired immunodeficiency syndrome. When someone has AIDS, they are more likely to get infections, and more vulnerable to unusual forms of cancers and other serious diseases.
If you think you may have HIV, you should get tested. Everyone age 13 to 64 should be tested at least once for HIV. If you are over 64 and are at risk for HIV, talk with your doctor. Your doctor can help determine how often you should be tested and help find ways to reduce your risk.
There are drugs that, when taken consistently, can help suppress the amount of HIV in your blood to undetectable levels, improving your health overall and making it harder to pass HIV on to your sexual partners.

By the time the older person is diagnosed, the virus may be in the late stages and more likely to progress to AIDS. For people who have HIV, it is important to start treatment as soon as possible after diagnosis. Treatment can help reduce the level of HIV in the blood to undetectable levels. When treatment makes HIV undetectable, the possibility of spreading the virus to a sexual partner becomes very low. This is known as treatment as prevention TasP.
Even when the disease is well controlled, people with HIV may develop aging-related conditions at a younger age. HIV and its treatment can also affect other parts of the body, such as the brain and the heart.
